Hot wallet vs. cold wallet: how to store your cryptocurrency
In this era of growing popularity of cryptocurrencies, it is becoming increasingly important to store your digital assets safely. Whether you are a long-term investor or a short-term trader, choosing the right wallet to store your cryptocurrencies is crucial. Today, we're going to look at the two main types of cryptocurrency storage: hot wallets and cold wallets. Understanding their strengths and weaknesses, as well as how to choose the best storage method for your needs, will help you protect your assets from hackers and other risks.
What is a hot wallet?
A Hot Wallet is a wallet that is directly connected to the Internet and is often used for everyday transactions and payments. Its biggest advantage is that it is easy to use and quick to access, making it ideal for users who need to make frequent transactions. Hot wallets include desktop wallets, mobile wallets, and web wallets, all of which can quickly transfer your cryptocurrency to an exchange or other address.
Because they are connected to the Internet, hot wallets are also easier targets for hackers. Although many hot wallets offer multiple levels of security (e.g. double authentication, encryption, etc.), they are still more risky than cold wallets. Hot wallets are a good choice for small transactions or short-term savings, but if you have a large amount of crypto assets, you need to be more careful with them.
What is a cold wallet?
A cold wallet is a wallet that is completely offline and is often used for long-term storage of cryptocurrency. It works by keeping private keys in an offline device, which greatly reduces the risk of hacking. Cold wallets come in two common forms: hardware wallets (e.g. Trezor, Ledger) and paper wallets. A hard wallet is usually a small USB device that protects the private key from outside intrusion. Paper wallets have the private key and public key printed on paper in the form of a QR code, which also protects against remote attacks.
Although cold wallets offer increased security, they have the disadvantage of being inconvenient to use, requiring the wallet to be connected to a computer or other device when transferring money. If you accidentally lose a cold wallet or damage a paper wallet, your cryptocurrency may never be retrieved, so you need to take extra care when using cold wallets.
Hot wallet vs. cold wallet: how to decide?
Whether you choose to use a hot wallet or a cold wallet depends largely on your needs and asset size. If you are a daily trader or need to make quick transfers, then the hot wallet is the better choice. It's easy to use and fast, making it ideal for active investors. If you are a long term holder and do not intend to trade frequently, then a cold wallet is a safer option, protected from hackers and cyber attacks.
For most users, the best practice is to split crypto assets into two parts, keeping a small amount of funds in a hot wallet for day-to-day transactions and a large portion of funds in a cold wallet, which ensures the liquidity of the funds and maximizes the security of the assets.
How to Protect Your Hot and Cold Wallet
Whether you choose to use hot wallets or cold wallets, security always comes first. For hot wallets, users should enable dual authentication, update their passwords regularly, and be cautious of downloading any apps from unknown sources, as this can effectively prevent the intrusion of viruses and Trojans. Avoiding cryptocurrency transactions on public Wi-Fi networks also reduces the risk of being attacked.
For cold wallets, keeping the private key is a top priority. Hard wallets need to be kept secure and you should avoid sharing your private key with others; paper wallets should be kept in a fireproof, waterproof place and consider keeping them in a safe deposit box at your bank. If your cold wallet is lost or damaged, you may not be able to retrieve your encrypted assets, so you need to back it up in advance.
How to choose the right encrypted wallet for you?
Choosing the right crypto wallet starts with considering your needs. If you trade cryptocurrencies frequently, a hot wallet is undoubtedly a more convenient choice. Common hot wallets such as MetaMask and Trust Wallet are suitable for most traders as they have a good user interface and a wide range of support.
Cold wallets are ideal if your goal is to hold on to your money for the long term and want to maximize the security of your funds. Hard wallets such as the Ledger Nano S or Trezor Model T offer a high level of security and support multiple cryptocurrencies. Some cold wallets also support a backup feature that allows users to easily recover lost funds.
Tip: Regardless of which wallet you choose, it's important to back up your private keys and helpers on a regular basis, as this is the last line of defense to keep your assets safe.
Frequently Asked Questions Q&A
Q1: Can I use Hot Wallet and Cold Wallet at the same time?
A1: Yes. Many users choose to keep a small amount of funds in a hot wallet for day-to-day transactions and a large portion of funds in a cold wallet for added security. This ensures liquidity and protects large assets from attack.
Q2: What should I do if I lose my wallet?
A2: If you lose your Cold Wallet, but you have a backup of your auxiliary word or private key, you can get your cryptocurrency back by recovering your Cold Wallet. Therefore, it is very important to have a backup token or private key and keep it in a safe place.
Q3: How do I know if my Hot Wallet has been hacked?
A3: Hot Wallet usually provides activity notifications and transaction history. If you become aware of unusual transactions (e.g. unauthorized transfers), you should immediately change your password, enable dual authentication and contact the wallet support team.
